Optical meron–antimeron pair in a plasmonic resonator

Caption

Isolated merons, anti‑merons and meron‑antimeron pairs are emitted from the plasmonic resonator which is excited based on symmetry engineering. Group-theory arguments further give symmetry classifications of the optical topological quasiparticles which can be identified as the irreducible representations of symmetry groups.
